Hi there,

We are recording a few webinars with Webex and the compression is really good.

 

The webex video file is recorded with the following specs - 1920 x 1080, 25fps, Data rate 69 kbps, Audio - 31 kbps, mono, Audio sample rate 32.000 kHz. A 20 min file is about 20 MB. It is tought to beat. 

 

I want to edit the videos and remove some parts with AME but the output file is really big...

I use the H.264 presets and tried to put the specs as low as possible. For instance, I use the following specs - 1024 x 576, 25 fps, Bitrate enncodig - VBR, 1 pass, Target butrate (the lowest) [Mbps - 0.19]. File is tripple the size.


Is there to retain the same compression so I dont end up when I remove 5% of the footage and republish with tripple the size file?

Thanks in advance
Bobby

I use Adobe apps for most of the things i do but sometimes other apps does the job far better. For your job i would have tried a app that smart render the media, iow do your edits and then just export the raw material without encoding it.

 

Download a free trial of TMPGEnc MPEG Smart Renderer 5 and test if it does what you want. You can perform simple edits and it will give you the same output as you put into it. The trial will work for 30 days and will not watermark the video.

 

Try it and report back your findings.

Hi there Averdahl,

I tested the TMPGenc and it does what is expected. There is no inflated file size

Thank you for the tip!
