To convert HEVC (H.265) recordings into H.264 files for YouTube, re-encode each video in HandBrake using an MP4 Creator preset that matches its resolution and frame-rate class. Then check the output files, upload them to YouTube, and add the uploaded videos to a playlist. A file extension change or container remux alone does not convert HEVC video to H.264.
What conversion changes—and what it does not
HEVC, also called H.265, and H.264 are different video codecs. OBS may record video in a container such as MKV; the container holds the video and audio streams, while the codec determines how the video is encoded. Remuxing can change a container without changing the video codec, so a remuxed HEVC file remains HEVC. You need to decode and re-encode the video to produce H.264.
YouTube recommends MP4 with H.264 for uploads and advises encoding and uploading at the same frame rate as the recording. See YouTube’s recommended upload encoding settings. OBS also recommends MKV for many recording use cases because it can be remuxed into a more compatible container; that remux is not a codec conversion. See the OBS Audio/Video Formats Guide.
Converting the files and creating a YouTube playlist are separate tasks: first make and verify the H.264 files, then upload them and arrange the uploaded videos in YouTube. The official sources cited here do not establish current YouTube Studio playlist menu labels, so use the playlist controls shown in your Studio account rather than relying on a guessed path.

Convert the recordings in HandBrake
1. Protect the originals and plan the outputs
- Keep an untouched copy of each HEVC recording. Create a separate output folder for the converted files.
- Use distinct, descriptive filenames that preserve episode or playlist order, such as 01-introduction and 02-lesson. Avoid output names that could overwrite the originals or another queued file.
- Note each source’s resolution, frame rate, audio tracks, subtitles, and whether it is HDR or 10-bit. Treat HDR and 10-bit recordings as a special case; the steps below are not a universal color-conversion recipe for them.
2. Open a source and choose a Creator preset
- Install HandBrake from the official HandBrake project. Open a recording as the source. Depending on the application version and platform, you may also be able to open a folder of videos.
- Select a Creator preset matching the source’s resolution and frame-rate class. HandBrake’s current documented Creator presets include 720p60, 1080p60, 1440p60, and 2160p60. The Creator family is intended for video-hosting uploads; its documented settings use MP4, H.264, and AAC stereo. See HandBrake’s official presets.
- Do not choose a 60-fps preset just because it is available if the source has a different frame rate. Match the preset class to the source as closely as practical, then inspect the settings before encoding.
3. Check video, audio, subtitles, and filters
- Video: Confirm the video encoder is H.264 (x264 or an available hardware H.264 encoder). Preserve the source frame rate and dimensions unless you have a specific reason to change them. Check crop, scaling, and filters so the output does not unexpectedly lose image area or alter the picture.
- Quality: The preset’s quality and encoder settings determine the trade-off between file size, encoding time, and visual quality. Do not assume that converting an efficient HEVC source to H.264 will make it smaller. OBS notes that HEVC can provide more compression efficiency than H.264; a comparable-quality H.264 encode may be larger. Slower software encoding can take longer, while hardware encoding can reduce CPU work but varies by hardware and driver. See OBS’s hardware encoding guide.
- Audio: Select the intended language and track, and confirm the output will contain sound. HandBrake can re-encode audio or pass through supported source formats; passthrough retains the source audio stream rather than converting it, but not every source format or track arrangement is suitable for every output. For broad MP4 compatibility, AAC is a straightforward choice. YouTube’s upload guidance also lists AAC-LC, Opus, and Eclipsa Audio. See HandBrake’s audio codec documentation.
- Subtitles: Check whether the intended subtitle track is selected and how it will be included. Do not assume every source subtitle will be present in the output without checking the settings and resulting file.
- HDR or 10-bit: Do not blindly apply SDR assumptions to HDR or 10-bit footage. YouTube’s guidance about H.265 for HDR concerns live streaming, a different workflow from prerecorded uploads; it does not establish a general HDR-to-H.264 conversion recipe. See YouTube’s live encoder settings.
4. Set the destination and queue the jobs
- Choose the output folder and a unique filename for the current source.
- Add the job to HandBrake’s queue. For a playlist batch, add each recording as a separate source/job and verify its destination name before starting the queue. HandBrake documents queueing and multiple-source workflows in Using the Queue.
- Review the full queue for accidental duplicate names, incorrect source-to-output pairings, and settings that differ from the intended batch. Start the queue when ready.
5. Test an output before converting the whole playlist
Convert one representative recording first. Watch and listen to the result, and check its duration, resolution, frame rate, aspect ratio, audio, and subtitles. If it looks and sounds right, use the same intended settings for the remaining playlist files. Keep the originals until the converted files have been checked and uploaded successfully.
Batch conversion with HandBrake’s interface or CLI
Graphical queue
The HandBrake interface is the safer choice when you want to inspect each source’s tracks and settings visually. Add files as separate jobs, give each a unique destination, and review the queue before starting it. This reduces the chance of silently using the wrong audio track or overwriting a file.

Command line
HandBrakeCLI can make a repeatable batch workflow, and the official CLI reference includes an x264 encoder. The exact arguments depend on your installed version, source track layout, color properties, and output paths, so verify the syntax against that version and test on one representative input before automating the rest. Do not use video stream copy for this conversion: copying the video stream leaves it HEVC. HandBrake’s documented MP4 defaults include AAC audio; confirm the actual output and log rather than assuming the defaults match every source.

- Upload the verified H.264 MP4 files to YouTube and wait for processing to complete.
- Check playback on YouTube, including sound and picture, before treating the upload as final.
- Use YouTube’s playlist controls to create a playlist or add the uploaded videos, then arrange them in the intended order. Playlist management happens after upload; it does not convert the files.
Using H.264 does not grant rights to music, video, or other material in a recording, and transcoding is not a way around YouTube’s copyright or monetization policies. Confirm that you have the necessary rights and review YouTube’s applicable rules for the content you upload.

Troubleshoot common conversion problems
- The output is still HEVC: A renamed file or remux changes neither the video codec nor the encoded video stream. Reopen the source in HandBrake, select an H.264 encoder, encode a new output, and verify the resulting codec.
- The picture is cropped, scaled, or has the wrong frame rate: Recheck the Video tab’s dimensions, frame-rate setting, crop, scaling, and filters. Match the source frame rate and dimensions where practical.
- The output has no sound or the wrong language: Inspect the Audio tab and select the intended source track. Decide whether to re-encode or pass through a supported audio format, then play the output to confirm.
- Subtitles are missing: Check the source’s subtitle tracks and the output subtitle selection. Confirm the result in a player before queuing the rest.
- A queued job overwrote another file: Stop and inspect the output folder. Assign unique names to every source, then rebuild or correct the affected jobs before restarting the queue.
- The H.264 file is larger than the HEVC original: That can happen because HEVC is more compression-efficient. Revisit the quality setting if the size is impractical, but compare the picture carefully; smaller output can mean lower visual quality.
- Colors look wrong in HDR or 10-bit footage: Stop before applying the same settings to the rest. HDR-to-SDR handling depends on color properties and conversion choices; the reviewed official guidance does not establish one safe recipe for every source.
- The upload does not match expectations: Verify the converted file’s codec, resolution, frame rate, audio, and completed YouTube processing. Upload bitrate guidance for live ingestion is not a target for encoding a prerecorded upload.
Or let it run in the cloud
If your goal is to keep a YouTube channel live from uploaded videos rather than convert a local OBS playlist for an ordinary upload, StreamNeo is a separate cloud option: upload a recording or build a playlist, add your YouTube stream key once, and go live. It loops uploaded videos; it does not stream from a camera.
