Hey guys!
I have some .ts HD videos here (720 and 1080) and I wanted to tag them with my logo, but I don't want to loose quality. What's the best way to do it? I tried to do it and exported the video in mpeg2, but the file size increased a lot. How to keep the same size and tag it?
Thanks!

h.264 really compresses the video files. Won't that make you LOSE quality. For example, I have a m2ts video file that I recorded (using my panasonic HD camcorder) that is 258MB and after converting to H.264 the file size dropped way down to 9.6MB! That HAS to decrease the quality, correct?
-
When the OP says he exported it as MPEG2 and the file size increased "a lot"...well, that makes me suspect the original videos are probably encoded as h.264. Which a lot of high definition video is now. But he hasn't given any specifics.
You want to keep the same size? I'd say h.264 then, it's very efficient. And any lossy compression will have a cost in quality regardless.Pull! Bang! Darn! -
All lossy codecs will result in a loss of quality. If you use sufficient bitrate the loss may be acceptable. The process involves first decompressing the original video then compressing it again with the new codec.
As far as file size is concerned:
file size = bitrate * running timeLast edited by jagabo; 2nd Dec 2011 at 19:30.

Ok, I am sure the codec used by my Panasonic HD is h.264, but why then I convert it to h.264/mp4 does it compress it even way further?

You are making many spec changes* there.
Start with what you are trying to accomplish? Small file sizes with crap quality?
video bit rate 30% of original
audio sample rate 48 to 44 CDLast edited by edDV; 2nd Dec 2011 at 21:54.

That is user error -
That is exactly my point. I know that going from an original source file size of 250mb down to 9mb will GREATLY decrease the quality. A small file size is NOT what I want. I want QUALITY HD VIDEO to be able to play on my bluray player WITHOUT things like the audio & or video stuttering happening.
I just don't understand why when using Full video converter 9 software, when I choose HD h.264/mp4 or ANY of the HD conversions, the file size DRAMATICALLY decreases. When I choose the general video conversions, like AVI, DIVX, MKV etc. the file size and bitrate stay the same or increase. Is it something screwey with this software?
I have figured out that if I slightly decrease the bitrate, from say 26 down to 23, the audio/video stuttering goes away and the quality is not decreased significantly. I just have to place these files into a different container (one that my bluray recognizes), like AVI or DIVX or MKV. -
Well you sort of hijacked the OP's thread... but anyway
Maybe you used the wrong settings, or the software sucks ?
Filesize = bitrate x running time
Current blu-ray players do not have to support 1920x1080p59.94. It's not in the blu-ray spec. Just lowering the bitrate doesn't guarentee anything. Consider getting a HTPC or media player like wdtv, asus oplay instead. This way you don't waste time re-encoding, and don't lose any quality -
You will probably have to manually select the frame size (keep it 1920x1080), frame rate (60 fps), codec (h.264), and bitrate (24.5 Mb/s). That will give you the same file size without much quality loss.

Thanks for all the replies...
The software I'm using to tag the videos and reencode is Proshow Producer. The .ts file I wanted to tag is 300mb and after reencoding it with the tag, the exported mpeg2 was bigger than 1gb...
Wich software would you recomend me to tag (watermark) the video and reencode it to h.264? -
-
thanks. I am getting a WD TV Live Media player next week, so I will see how the m2ts 1920x1080 60P video files play.
-
Some 1080p60 videos play well on my WDTV, some have problems. If you upload a sample I'll try playing it and let you know if it works.
-
One issue I'm seeing with 1080 60p samples is they play for a few minutes, then lock up. It may be a device memory buffer issue. This happens even at reduced 17 Mbps bit rate.

just to give you heads up, new model WDTV Live streamer has still major issues regardless playback, I saw WDTV Live plus still on the shelf in Best Buy next to that new one WDTV Live streamer , it can give you some frustrating time before WD fixes that,
Best Buy purchase gives you an opportunity to try it and exchange it or to return easily
