MPEG2 to H.264 (or x.264) FLV- how to do that?

[spycam]

I have MPEG2 videos (taken from DVD) and i want to resize them, watermark and convert/render to h.264 FLV.
How can i do that?

If you just want to watermark with a text logo you can use SUPER, load your dvd vob files, select flv as container and h264 video and aac audio, click on DirectShow Decode and click on the D-button next to it to add the watermark. Convert.

If you want an image logo

Familiar with avisynth? Then use it. See https://forum.videohelp.com/threads/305986-adding-watermark-while-ripping .Export to a mp4 with h264 using megui. mp4 works fine in flash also.

If it's too complex then you can try virtualdubmod, https://forum.videohelp.com/threads/191496-Put-a-custom-watermark-on-your-video . Export as avi and convert to mp4 or flv with another converter.

Well, i can render the video with watermark and all the filters and things to H.264 Mpg4 in Sony Vegas Pro.
But the problem is that i don't know how to place the video/audio to the FLV container.

Also, in H.264 FLV video, the audio should be AAC?

you can try format factory. I think that outputs to flv. I know I've converted to other formats with flv as the input source so I think it can output as well. Though the watermarking you'll have to do with other programs.

yes aac audio is fine

are you sure you *need* flv container? many flash front ends work fine (some better) with .mp4 container

to mux into flv container you could use ffmpeg (command line tool)

ffmpeg -i input.flv -vcodec copy -acodec copy output.flv

if this is for streaming web , you need to inject metadata or it won't play right away (will need to be downloaded completely first). You could use flvtool++ , flvtool2, yamdi, or flvmdi to do this

Well, I can't read your mind that you already had solved half of it...

I will need to use the FLV videos for streaming on FlowPlayer and other flash players, as i thought, the injection is needed for "seeking" feature in the video, to fast forward to some other parts or so, but in my case, it wil be like 1 minute clips, most players (flash) are buffering some video data before showing, i'm not sure if i really need the injection

[poisondeathray]

are you using true streaming (rtsp) , psuedostreaming or progressive download (http) ?

most common and least expensive is http progressive download

initial buffering is a server side delay , this is different than waiting 100% for download before it plays. You set this value when setting up the code. e.g. on youtube or related sites, there is a short delay, but you can start playing immediately. If there was no metadata, or moov atom wasn't at beginning, you would have to wait until 100% downloaded before it starts to play

mp4 in general works fine in flowplayer for streaming, for progressive download case. Youtube uses .mp4 for their pseudostreaming

mp4 from vegas does not (have to wait until 100% downloaded), because metadata (moov atom) isn't at the beginning by default. To get around that you have to either remux from mp4box (yamb) or mp4faststart

Thank you for explanation.
So, it means that if i want to render mp4 video and them cut it to clips, i will need to use mp4faststart for every clip, right?

[poisondeathray]

from vegas, yes

note if you are using true streaming , or pseudostreaming for large files, flv container seems to work better, but for the majority of sites which use http download, mp4 is preferred (also Adobe recommended)
