Different frame rates and sizes for the EX1?
Hi I’m looking at different recording frame rates and sizes.
I currently record in HQ1920 x 1080 /50i and I’m wondering for what application would I use 1280 x 720 /50p or 1280 x 720/25p. And what shutter speeds should I use with this format. I know that the resolution is smaller but as I go to DVD anyway what would I gain using this format with the EX1? I love this camera but the down conversion to DVD is shocking after seeing footage in HQ 1920 x1080 Thanks |
Shooting 25p will allow you to do overcranking or slow motion shooting at up to less than half of real time. Shooting progressive has lots of intrinsic benefits if your final is going to end up both online and on DVD. Shooting at 25 frames will allow you to get more or a film look, if that is what you are after.
Shooting 1080 progressive gives you a lot of flexibility with your final output. 720 progressive is good if you are doing a lot of overcranking. You also gain more stops (light) as you bring the frame rate down which can be really helpful. I've found the best way to get a handle on it is to shoot in the different modes. |
Hi Andy,
By bringing the frame rate down do you mean? 1920 to 720 I gain more light? Yes your right testing. |

Last week I recorded a test interview. Shot under tungsten light, so not ideal, but still quite clean and detailed. I used the following workflow: 1. Load XDCamEX footage into NLE 2. Render uncompressed 1080p file (compare to original... identical) 3. Take uncompressed file into Lanczos resize and change it to 720x405) 4. Do a slight de-noise on the footage to ensure it's clean 5. Bring 720x405 clean footage back into NLE 6. Render progressive widescreen mpeg2 file and AAC audio file 7. Open DVD Authoring program and load in mpeg2/aac files 8. Create .iso file so I don't have to burn a real disk. 9. Open .iso file in VLC The image was gorgeous. I could even see the stray shirt fibers from wear on my collar. And each gray hair on my head was plainly clear. I could see my individual pores also. So I am not sure what others are doing to produce their DVDs, but my workflow gives me results I am THOROUGHLY proud of. And I will be producing some corporate DVDs next month with this exact workflow. |
Hi Perrone,
Sounds like you have a great workflow, I have just moved over to FCS from Vegas. After seeing footage in it's glory from the EX1 and then seeing the end resulting DVD leaves me heart broken, I'm interested in your workflow. What's Lanczos? |

Shooting in 1080i or 720p?
What's the better end product with the EX1 for down conversion to SD DVD. This might seem silly but will 720p render out better quality SD than 1920? I feel that the software is lagging behind camera devolpment and I think for myself this wonderfull camera is not showing it's true image at converted HD, to SD DVD. How can these movies we get from the video shop look so clean. These films are shot on high grade cameras, HOW DO THEY CONVERT to SD DVD? Man |

I get good DV from FCS in this workflow:
1 Edit clips in timeline with XDCAM EX settings, but you do not have to render. 2 Create a DV sequence with these settings: - Frame size - choose "CCIR / DV PAL (5:4)" from the menu and you get 720x576. - Pixel aspect ratio : choose "PAL - CCIR 601 (720x576) from the menu and check "Anamorphic 16:9". - Field dominance "None" - Editing timebase "25" - In QuickTime Video settings: click the button "Advanced" and choose "Apple ProRes 422 (HQ) - (don´t know if HQ is necessary) 3 Open this DV sequence and add your XDCAM EX sequences to it by dragging them to the canvas. You will get the question if you want to change the DV sequence settings to those which you are adding: then click the "No"-button 4 Render 5 Export to a QuickTime reference file (some people suggest a self-contained, but I find reference files have the same quality and they are smaller and faster to export) 6 Open Compressor and use one of the DVD settings; however I find that adding a sharpening filter with the "5" setting is worth it. 7 Add m2v and audio files as assets in DVD Studio Pro. |

The frames build from the 720x480 pixels on a NTSC-DVD (or 720x576 in PAL-area) are displayed either as 4:3 or as 16:9 depending on the setting of your TV. But 720/480 is 3/2 which is neither 4/3 nor 16/9. So in any case those pixels won't be displayed as squares. So if you want 16:9 letterboxed to 4:3, then you must resize your 1920x1080 footage to 720x360 (and add black bars to get 720x480). But if you're using letterboxing then you're wasting lines, because you make them black instead of filling them with information. So you're loosing vertical resolution. You have to resize your 1920x1080 footage to 720x480 to get the highest resolution on a 16:9-TV. Your DVD-player (if properly configured) will letterbox it automatically if it is attached to a 4:3-TV. |
