4K Resolution scaling problem with TIFF images - ortelius - 2016-08-31 Hi, I am using original resolution TIFF files generated by LR and render the sequence with LRTimelapse to 4K (4096x2304, ProRes 422). While uploading some footage to Videoblocks, I get an error because the resolution is not exactly 4096x2304px. Example: Original resolution of the TIFF images (aspect ratio 16:9) generated by LR: 5220 x 2936 px ---------------------------- Error from Videoblocks: Invalid Resolution (4096.348773841962x2304) --------------------------- This is exactly the resolution you get by down scaling 5220 x 2936 px to 2304px high without rounding. This problem does not happen for sequences rendered from JPEG files in original resolution... The render option 'Force output to 16:9' in LRT does not make any difference. Possibly exporting TIFF images in LR with 4096 x 2304 px may be the solution, but I want to keep to source file resolution as large as possible. Thanks for any help! Rainer RE: 4K Resolution scaling problem with TIFF images - Gunther - 2016-08-31 Which resolution did you choose in the LRTimelapse render dialog? RE: 4K Resolution scaling problem with TIFF images - ortelius - 2016-08-31 I'm using 4096x2304 in LRT render dialog. Just have seen exporting from LR in TIFF is only possible in original resolution. So no option for my problem. RE: 4K Resolution scaling problem with TIFF images - Gunther - 2016-09-04 Hmm, I've tried to reproduce that but couldn't yet. I've exported a 16:9 cropped sequence via LRTExport as TIFF intermediaries and then rendered as ProRes 422. When checking the Width and Height of the MOV file via MPC player (VLC should do too), I get exactly 4096x2304. Could you please tell me which settings you used in the LRTimelapse render dialog? Could you try checking the dimensions/properties of the files in your player? Code: Format : MPEG-4 RE: 4K Resolution scaling problem with TIFF images - ortelius - 2016-09-04 Thanks for checking. These are my render settings for a cropped TIFF sequence. The TIFF images have been generated by LRTimelapse export plugin from LR, cropped from Canon .cr2 files with 16:9 aspect ratio. Image size in this case is 5193x2921 pixels. [Image: https://s10.postimg.org/hxmifwlwl/render_settings_1.jpg] This is the properties dialogue box of the MPC player (Shift+F10) for this sequence: [Image: https://s3.postimg.org/amfwef6cf/preferences_mpc.jpg] It shows 4096x2304 pixels, but this seems to be rounded and positions after decimal point are not shown. But it gives a value for the aspect ratio if it is not exactly (16:9) -> in this case (262136:147447). In case of JPEG rendering, no aspect ratio is shown in the lower box, since it is exactly (16:9): [Image: https://s21.postimg.org/b6ztr87mb/preferences_mpc_from_jpeg.jpg] No difference if 'Force output to 16:9' box is checked or not. RE: 4K Resolution scaling problem with TIFF images - Gunther - 2016-09-04 Could you please send me 2 or three of those Canon RAW files including their XMP files via Dropbox or Wetransfer. RE: 4K Resolution scaling problem with TIFF images - Gunther - 2016-09-06 After analyzing this I found that the sequences are all being rendered in the correct and exact 16:9 ratio. The only thing that could happen is, that the aspect ratio itself is being written as a weird fraction into the metadata by the encoder. In the next update (4.7.2) I will force the ar-metadata to be written as 16:9 into the file, so that your stock agency will accept them. RE: 4K Resolution scaling problem with TIFF images - ortelius - 2016-09-06 Thanks a lot for your fast support and hard work, Gunther. Problem solved for me, Videoblocks accepting the sequences now. Rainer RE: 4K Resolution scaling problem with TIFF images - Gunther - 2016-09-06 Remark: Rainer has got a beta version with the fix from me. If anyone else needs this before the next official update, please let me know. RE: 4K Resolution scaling problem with TIFF images - disasterdom - 2016-10-03 hi guys, i have just encountered this problem as well. i am using a nikon camera. Uploaded a clip to video blocks and got rejected with this message "[font=Roboto, sans-serif]Invalid Resolution (4096.254409937888x2304); For mp4 formats, footage must have one of the following resolutions: [3840x2160, 4096x2160, 4096x2304]."[/font] |
