Hi guys,

I evaluated AVS Video Editor and was very happy with it, so I purchased it. However when I finally go to 'Produce' my movie the output quality is horrible.

By trying all sorts of different output formats and options, I have traced the problem all the way back to the Editor itself. Please see attached screenshot. You can see the Editor showing the first frame of a clip. Then I have opened the same MTS file in Windows Media Player and hovered it over the window for comparison.

Note the original MTS file (bottom) has significantly clearer trees and T-Shirt. The AVS version (top) has a lot of 'ghosting', as if it is between two frames. This 'ghosting' effect continues all the way up to the burnt Blu-Ray disc, and looks terrible on my TV.

I am very disappointed with this quality. I had thought it would only be for the preview, not the final output! Has anybody had this same problem and/or can you please advise what is causing it?

Regards,

Richard.

I should point out this 'ghosting' effect is *not* present in other video editing programs on the same computer, such as Pinnacle Studio.

The 'ghosting' effect is also *not* present using other file formats in AVS Video Editor, such as .mp4.

If it helps, the ghosting effect is noticeably better when opening the same MTS in AVS Media Player as opposed to AVS Video Editor. See attached screenshot.

Presumably these two applications are using quite similar code? Does that give you any clue?

Just to let you know I have uploaded the MTS file to ftp.avsmedia.com as instructed.

I have also tried a clean install of AVS Studio on to a completely different machine (different chipset, graphics card, drivers etc). I installed it on my laptop. The exact same problem is evident.

Regards,

Richard.

Esther,

Thanks. I have uploaded the MTS file as instructed. I have provided screenshots in the forum messages above.

I should stress that I have no problem with this 'ghosting' effect during video *editing*. Indeed, if the ghosting is a tradeoff for the speed and fluidity of the UI then it is well worth it. The responsiveness of AVS Video Editor is better than all the other editing suites I tried, and a key reason I purchased AVS. Pinnacle, VideoPad, Movavi, Nero and Corel VideoStudio simply cannot compete with your MTS editing. So please don't change anything there!

However, it is when this same ghosting effect ends up on the final Blu-Ray disc that I have a problem. I would have expected the 'Produce' phase to go back to the original MTS files and re-render them. Not in a 'preview' mode but in a 'final, high quality' mode.

Regards,

Richard.

Hello,

Thank you very much for your comments and positive feedback.
We have received the file and passed it on for testing.

We will contact you in Online Support System as soon as the results are ready.

Best regards

Thanks, some more clues if it helps (I'm a software developer myself, so I know how little details can be useful!):

1. My camcorder is the Panasonic HDC-SD90: http://www.trustedreviews.com/panasonic-hdc-sd90_Camcorder_review
2. It appears the MTS files may be "1,920 x 1,080 Full HD resolution with 50i interlaced fields". Interlacing may explain the appearance of two frames in one?

Regards,

Richard.

Hello,

Thank you for the information.

Best regards

Thanks for the patch.

I am delighted to report the problem (which I assume from the filename *was* an interlacing problem?) is now fixed. Each frame looks perfect! Thanks!

Unfortunately the output is still unacceptable. There is a further issue that *was* evident before, but I was hoping was related to the interlacing issue. However it is *still* there even after the interlacing has been fixed.

The problem is the output 'skips' regularly. About once a second. If I had to guess what was happening, I'd say it's because the original MTS file is encoded at 25fps. Apparently this is normal for European/Australian camcorders (the PAL format). However I note that the Blu-Ray standard is for 24fps (or 23.9). I am reading on various forums that video software should compensate by adjusting the timing of the output. However AVS Studio doesn't appear to do this? It's like it's just dropping the 25th frame entirely?

The effect is very noticeable on pans, or scrolling text, or fast moving content. It appears as a 'skip', or 'stutter' of the frame rate. It does not happen with other video software.

I will upload the same video* produced by Pinnacle Studio 15 (works great) and AVS (stutters), as well as the original MTS files, for you to review. I hope you can see the stuttering either visually, or by inspecting the file. It is very obvious on my Sony Blu-Ray player. Windows Media Player also balks at the AVS version.

I have tried a number of things. The most promising was to use AVS to encode to file, choose M2TS, and set the frame rate to 25fps. However the output still looked the same. This leads me to believe AVS is actually ignoring the 25th frame altogether.

Thanks for your quick responses so far. I am very encouraged by your support. However if this second issue cannot also be resolved then AVS is not acceptable to me.

Regards,

Richard.

A clue: I tried downloading AVS Video Converter 8.3 and converting the Pinnacle.m2ts (that I uploaded, and works fine) to 'Blu-ray Full HD 1080p (H.264, 24000 kbps, 24fps)'. It produced the exact same 'stuttering' as the AVS.m2ts version. So this doesn't appear confined to AVS Video Editor per se.

I further tried hacking profiles/blurayprofiles.xml to add a 25fps option with a <FrameRate> and <Bitrate> to suit. It produced the same output. Mind you, there are a lot of other options in there I didn't know what to put for!

I'm happy to try something if you can suggest a <profile></profile> block?

Or maybe it makes no difference if the problem is related to the source, not the output?

Hello

I'm too suffering from this same 'ghosting' effect when either using the AVS Video Convertor or the Video Editor. The input file type is M2TS, shot with a Panasonic HDC-SD41 in AVCHD 1920x1080 25fps mode. This ghosting doesn't exist in the raw M2TS file, only after converting & it doesn't matter what format I save it in. I've uploaded the 2 example to YT, the first is the untouched M2TS file, the other converted, where you can see the ghosting (pause the video as the car comes in to view):

Any help would be appreciated please. Thank you.

Dear user,

Please note that the preview window of AVS Video Editor shows cached copy of your video and it can not influence to ourput file quality.

To get the created video of better quality please try to select the input file parameters like video bitrate, frame rate and frame size to be the same for the output, to do it press the Advanced button after selecting the format. To check the input file parameter right click on the file while in AVS Video Editor - choose Properties.

Inform about the result please.

Kind regards

I'm afraid I forgot to say that I have tried that too with exactly the same result.
