Video_TS and HandBrake

[RunAway]

I am rendering my home movies into m4v files with HandBrake and the size of the file is only about half of the video.TS folder I convert...My question is do I loose much by doing this? Its hard to tell a difference on a CRT and I dont know much about this stuff but isn't the MP4 suppose to be a loseless format to a great degree? Thanks...

No, H264 is not lossless unless you use the lossless setting, in which case you will get a file that is identical visually, but several times larger than the video_TS folder you are converting.

Any conversion from a lossy format (e,g, mpeg-2) to a lossy format (e.g. H264) will incur some level of data loss. How much depends on a lot of factors, including the amount of compression applied to the source s, the amount of noise or artefacts in the source, the amount of action in the source, the amount of compression applied during encoding, and the codec chosen.

If you wish to minimise quality loss, encode using a quality based encoding method (H264 encoders support this) and chose a quality level that is visually lossless. You wont have any control over the output size, and depending on the source you may get a lot less reduction in some cases, but you will get a better quality output.

Thanks for your reply...I have another question if I may.I just got a Flip Ultra HD Pocketcam that puts out HD 720p MP4 files that are way better than my Canon FS100 that I burn to DVD..In order for me to put these MP4 files on a DVD I have to convert them to work in Pinnacle Studio 11 Plus...I loose a lot of quality that way...I would like to keep the same HD quality but don't know what all I need to do or how...No point in having a HD camera if I have to down size the video..I have a Blu Ray player (not burner) in my computer and an HDCP compliant video card with my 37" Sharp HDTV as an HTPC that I would like to use my new HD camera with...I can burn the MP4s straight to a DVD and play each indivdual file with VLC player but I would like to make menus and chapters and stuff....

maybe use multiavchd to write the flip videos to dvdr media to use in the blu-ray player.
