For a straightforward SDR upload, MP4 with H.264 video and compatible audio is a sensible target. These steps prepare files for upload; they do not start a YouTube Live stream. YouTube’s cited encoding guidance is general, not India-specific, so there is no special India-only codec or bitrate in these recommendations.
What batch conversion does—and does not do
Batch conversion runs the same FFmpeg operation on multiple files. It can make files more compatible or change their encoding, but it does not upload them or send a live stream to YouTube. The recommendations below are for preparing uploads, not YouTube Live ingestion.

FFmpeg normally transcodes selected streams unless you specify -c copy. Transcoding decodes and re-encodes media; stream copy carries the existing encoded streams into a new container without re-encoding. Copying is quicker and avoids another lossy encode, but only works when the existing streams suit the target container and platform. [FFmpeg documentation]

A practical SDR starting point
For a typical standard-dynamic-range (SDR) upload, use an MP4 container, H.264 video, and compatible audio such as AAC. YouTube recommends progressive scan, H.264 High Profile, two consecutive B frames, a closed GOP with a GOP length of half the frame rate, CABAC, variable bitrate, and 4:2:0 chroma subsampling. Its supported audio options include AAC-LC and Opus, with a recommended sample rate of 48 kHz. Eclipsa Audio is listed for eligible contexts. [YouTube upload encoding settings]

Match the frame rate to the recording where possible: YouTube’s guidance says, “Content should be encoded and uploaded in the same frame rate it was recorded.” Common rates it names include 24, 25, 30, 48, 50, and 60 fps; other rates are also acceptable. Deinterlace interlaced footage before uploading—for example, YouTube gives 1080i60 to 1080p30 as a conversion example. [YouTube upload encoding settings]
For SDR, YouTube recommends BT.709. The following are its upload video-bitrate recommendations, not minimum requirements, broadband-speed rules, or guarantees about playback quality. YouTube’s page was accessed in 2026; it does not state a publication year in the page content reviewed.

YouTube’s standard computer aspect ratio is 16:9, but its player adapts to other shapes, including vertical and square. Keep the source composition unless you deliberately want to crop or stretch it. Avoid forcing a new resolution or frame rate simply to make every file identical if that would change the footage unnecessarily. [YouTube upload encoding settings]

When to copy and when to re-encode
- Try stream copy when the source video and audio codecs are already suitable for the chosen container and upload. It avoids another lossy generation, but does not change quality, resolution, or codec.
- Re-encode when a stream is incompatible, you need to change its codec or settings, or a test upload shows a compatibility problem. Re-encoding takes processing time and can reduce quality if settings are poor.
- Do not assume one profile fits every file. Multiple audio tracks, subtitles, HDR, variable frame rate, unusual codecs, and incompatible stream/container combinations may need different mapping or handling. FFmpeg warns that incompatible options can fail or produce invalid outputs. [FFmpeg documentation]
Install and check FFmpeg on Windows
- Install a Windows FFmpeg build using a source you trust, and make its
binfolder available on your PATH if you want to run it from any directory. - Open Command Prompt and run
ffmpeg -version. If Windows reports that the command is not recognized, use the full path toffmpeg.exein the examples below or correct your PATH, then open a new Command Prompt. - Create an input folder, such as
C:Videosto-convert, and a separate output folder, such asC:Videosyoutube-ready. Keeping outputs separate prevents the batch loop from picking up its own results.
Convert one file before processing the folder
In Command Prompt, try a single-file conversion first. This illustrative SDR command uses H.264, AAC audio, and MP4 with Fast Start. It preserves the input’s dimensions and frame rate rather than forcing them; the example bitrate is a starting point for 1080p SDR at a standard frame rate, not a universal setting.
ffmpeg -i "C:Videosto-convertsample.mov" -c:v libx264 -profile:v high -pix_fmt yuv420p -b:v 8M -maxrate 8M -bufsize 16M -c:a aac -b:a 384k -ar 48000 -movflags +faststart "C:Videosyoutube-readysample.mp4"

For high-frame-rate 1080p SDR, use YouTube’s 12 Mbps recommendation as the video-bitrate reference instead; for other resolutions, use the relevant row above. These values are upload recommendations, not a command-line guarantee that every source is best served by that rate. If the source is mono or 5.1, choose audio settings appropriate to that channel layout rather than blindly applying the stereo example.

Batch-convert a folder with a Windows .bat file
The following example is for a saved .bat file, not a command typed directly at the interactive prompt. In a batch file, the loop variable uses %%F; at the prompt it would use %F. Save this as, for example, convert.bat, changing the folders and profile to match your files.
@echo off
set "INPUT=C:Videosto-convert"
set "OUTPUT=C:Videosyoutube-ready"
if not exist "%OUTPUT%" mkdir "%OUTPUT%"
for %%F in ("%INPUT%*.*") do ffmpeg -i "%%~fF" -c:v libx264 -profile:v high -pix_fmt yuv420p -b:v 8M -maxrate 8M -bufsize 16M -c:a aac -b:a 384k -ar 48000 -movflags +faststart "%OUTPUT%%%~nF.mp4"
- Save the file with the
.batextension, not.txt. - Confirm that
INPUTpoints to the source folder andOUTPUTis a different folder with enough free space. - Run the batch file from Command Prompt so you can read FFmpeg’s progress and error messages.
- Inspect several outputs, including files with different audio or video characteristics, and test a small upload before scaling up.
This simple loop treats each matching file similarly and uses the filename stem for the MP4 output. It is not a full media-library workflow: unusual files may need specific stream mapping, subtitle handling, HDR-aware settings, or a different profile. Shell quoting and escaping can require an additional layer when commands include filters or other special characters. [FFmpeg utilities documentation]

Hardware encoding may be available, but neither its presence nor its speed or quality advantage is universal. FFmpeg’s documentation includes Windows Media Foundation hardware-encoding examples; support depends on the installed FFmpeg build and the computer’s hardware. Check the encoders available in your local build before changing the command, and compare a short sample rather than assuming a hardware encoder will be faster or look the same. [FFmpeg all-in-one documentation]
Troubleshoot common batch-conversion problems
- “ffmpeg is not recognized.” Windows cannot find the executable. Add its
bindirectory to PATH, open a new terminal, or callffmpeg.exeby its full path. - The batch file finds no inputs. Check the
INPUTpath and the wildcard. The example matches files in that folder, not nested subfolders. - Outputs are missing or overwritten. Verify the output directory and filenames. Keep it separate from the input directory, and avoid running multiple files with identical filename stems from different source locations into one destination.
- Conversion fails on one file. Read the error for the stream or option that failed. A file with multiple tracks, subtitles, an unusual codec, or HDR may not fit the example profile; handle it separately rather than assuming a single command can safely process every source.
- Audio is absent, wrong, or out of sync. Inspect the source’s audio streams and test an individual file. The example relies on FFmpeg’s default stream selection; files with multiple tracks may need explicit mapping.
- The output is larger or looks worse than expected. Re-encoding changes the encoded stream and can add generation loss. Review bitrate, source quality, and the YouTube recommendation appropriate to the resolution and frame-rate class; do not increase bitrate expecting it to restore detail missing from the source.
- The result is rotated, stretched, or cropped unexpectedly. Check the source orientation and dimensions, and remove forced scaling or aspect-ratio filters unless you intentionally want that change.
- YouTube flags a rights or monetization issue. Conversion does not grant permission to use music, footage, or other copyrighted material, nor does it make reused content original. Use material you own or are licensed to use, and review YouTube’s applicable copyright and monetization rules before publishing.
Or let it run in the cloud
