Hello

What do I need to select in KDENLIVE when saving the movie to upload it afterwards in youtube with a good quality?

Regards,

jm

Youtube uses H.264 encoding in their video and AAC for audio, so those are probably best choices to use in kdenlive too at the moment.

For normal resolution you can use setting H.264 from 400k to 1000k. For 1280×720 HD material you should use higher bit rate like 2000k.

Helpful links to decide what bit rate to use:

Hello fuli

Ok. I will try that

So I have to click on render, then on H.264 2000k

Youtube will re-encode everything on their side. So all you can do is to send them as good video as possible. You can use higher bit rates too, but that will make uploaded file size bigger. Some say you should use 4000k or even 6000k for the best result for Youtube HD material. 2-pass rendering also makes better quality video, but it may take twice as long to render the video. Youtube will accept file sizes up to 1 GB.

Youtube warns not to mess video frame rate during editing process. Check original material for frame rate and use MLT-profile with same frame rate and progressive checked (PAL / NTSC selection on Kdenlive rendering window does not seem to change frame rate).

Youtube will use 44100 Hz sampling rate for audio, while Kdenlive default settings for H.264 AAC audio sampling rate is 48000 Hz (DVD). If your original audio uses 44100 Hz (CD), you can make new rendering profile by editing current one to avoid re-sampling audio 44100 -> 48000 -> 41000. If audio is important you can also increase bit rate for HD material rendering profile from 128k to 232k.

Most people will probably be satisfied to quality from preset H.264 rendering profile with 2000k video bit rate.

Hello

The files are too big with H264 and 2000k.

Is there no better solution to get good quality in youtube?

When I upload from my camera sony cyber-shot directly, the quality is very good. But I need to use KDENLIVE to cut and correct the video.

Thanks

What do you mean "they are too big?" YouTube now accepts 2GB upload[1], but still only 10 minutes. There is no way you are exceeding the upload size for 10 minutes of 2 Mb/s:

10m * 60s/1m * 2Mb/1s * 1B/8b = 150 MB

I actually suggest higher bitrate when uploading 720p if you have a decent upstream bandwidth.

"too big" means it takes too much time to upload.

What selection do you recommend for good quality and still not takeing so much time to upload?

defiantly 2 pass render, quality to size will be much better. are you wanting HD version?
if standards good enough 400kbit/s is all you need. 256kbit/s on audio.

look at the wiki link above double the bit rate will give you sufficient quality that there encode will pretty decent. remember that the total bit rate is audio and video.

If you do not want to wait that long to upload, then I suggest you reduce the bitrate and NOT upload a 720p for HD. You cannot get something for nothing. You are better off with a lower resolution (perhaps 640x360 for 16:9 and 640x480 for 4:3) for your reduced bitrate rather than suffer from heavy compression artifacts. And like alabandit sez, use dual pass.
