Do Video Converters Degrade the Original Clip's Resolution or Quality?

I've uninstalled QuickTime since the latest notification of the security vulnerabilities were broadcast. My problem is that the FujiFIlm XP70 that I have captures in MOV-QT format. So if I try to drag and drop them into a timeline in a project, I get the expected error - attachment Err1.

So I thought a work around would be to convert the MOV to a different mp4 format. I went to this site "http://www.online-convert.com/result/579e2f69011a9f547ac03bcb6a2a771d" and converted the MOV to a mp4 file. MediaInfo taken before and after the conversion confirms that this happens. I can then successfully drag and drop the converted mp4 file into the PD13 timeline and work with it from there.

But I get to thinking and wonder if any sharpness, resolution or clarity of the original clip is reduced in the process. Does any of that happen due to codecs used in the conversion process? Am I even asking this previous question properly? - if not, please educate me so I don't sound so ignorant in asking such things.

Thanks

answer is YES and Yes.

converting one container, MOV, to others, MP4, and between the codecs will degrade to a 'level of the conversion'.



for me, I still use Samsung movie converter v1.0.0.13 or Rockymountains movie converter v0.2.02.0 to

convert H.265 to H.264 at HQ setting with high bitrate. example original H.265 MP4 bitrate @ 50Mb/sec

after the conversion, it comes out to 160 - 200Mb/sec H.264 MP4. too low or too high bitrate also sucks.

in the process, I do lose slightly video sharpness and saturation.



How? just play the converted and original side by side...



you can also try free converter HandBrake!



FYI, I have a slow PC.

when the video bitrate is huge, ex. 4K @200Mb/sec, then the PD struggles to render on the preview pane.

I do a work around. creating FHD video is extra time spent but it makes the editing much smoother and faster.

after editing is done then save and close the PD. move the FHD video to different folder and place the converted

video with same file name as FHD to the folder you've just worked on. open the .PDS file. PD loads and produces

your 4K masterpiece.

Any file converter can cause a loss because of rerendering. Converting mov to mp4 can be lossless if you are only changing the container of the video file and not the encoding. PD14 of at least the last 3 builds can do a lossless conversion of mov to mp4 because svrt can be available.

The online conveter you used in that link read that the file is deleted at your request so we don’t have a sample to check out for you. I would think that the bitrate must be reduced to allow a faster transmission speed.

Users in this forum like to use handbrake, a freeware to do the conversion. Apple QT Pro for $30 claim to be able to do it as a lossless conversion and as do some others. We find that it isn’t the case on the pc version for all mov file types to import to PD. PD14 lossless conversion is not available for all mov files.

Wow, let’s hope that this post does not turn into another stinkburger like the 37 thread one you visited lately. Other users and contributors may be able to suggest a lossless mov to mp4 converter that works and is freeware.

I see that PepsiMan has responded while I was still typing. He is right.

PepsiMan - tomasc

Thanks for the replies.

PepsiMan- I'm guessing that Samsung movie converter v1.0.0.13 or Rockymountains movie converter v0.2.02.0 are a 'pay to play' sort of software. Probably worth it in the long run but I gotta try to do the cheap thing at least once (freeware versions of similar software).

Sorry about that tomasc - I usually delete stuff I upload after I get my result. However, I just converted another file and left it there if you wanted to try dld'g it and see how it holds up.

I think it should be at: http://www.online-convert.com/result/706634005b1757584658f7786f1e8229

This is a different file/video clip than the one in the OP. It is NOT a very good video but the benefit of this one is that it is only 9 seconds in duration!

I've seen the mention of handbrake before in this forum - will check that out. So are you saying Handbrake does a lossless conversion from MOV to mp4???

tomasc mentioned that "Converting mov to mp4 can be lossless if you are only changing the container of the video file and not the encoding." - so this begs the question: Does online-convert do this container change without encoding (or would this be re-encoding???) ?

THanks again guys.

Just saw the MediaInfo on the converted file and it doesn't look good for it being close to the original as far as the numbers appear.

Original clip: file size-14.2MB, overall bit rate-13.2 Mbps, FOrmat profile - QT, Codec ID- qt 0000.00 (qt)

COnverted clip: fs - 9MB, overall bit rate- 8.358 Mbps, FOrmat Profile - Base Media, Codec ID- isom(isom/iso2/avc1/mp41)

Have you thought of trying optodata's Magic+PD? The conversion is to AVI and lossless. You can download the trial version that has a watermark just to test it. If it doesn't work for you there's nothing lost.

You can then produce to whatever format suits you. The only down side is the large size of the AVI file, but you just delete them when you have finished your project.

Worth a shot, CS

Up till this point I haven't really felt like I had the 'need' to use the Magic+PD Robert. I'm not processing 4k (yet... and probably a long time away form doing this) - but I've seen the comments on the assistance it has on that sort of processing.

So the Magic+PD can take a MOV file input and convert to AVI? I don't mind the temporary file size issue. This might address the preview 'glitchiness' that I experience with large projects in previewing them also.

Just might have to take a look at it when I get home. Thanks for the suggestion Robert!

Just tried it with a .MOV and it works perfectly.

If you need any help you know where I am. Download from here http://forum.cyberlink.com/forum/posts/list/46177.page Make sure you take the correct bit version for your machine (see snapshot)
